Abstract:
In recent years, due to the increasing number of computers and smartphones which can detect Wi-Fi signals, wireless local area networks (WLAN) have been installed almost everywhere. WLAN based indoor positioning systems have been widely investigated and used, because of their accessibility, low cost and not requiring any additional hardware support. This study presents a Wi-Fi based trilateration method for indoor positioning using Received Signal Strength (RSS) measurements. The distances between Access Points (AP) and the mobile device were estimated from evaluated RSS values by signal propagation model. The position of the mobile device was estimated using these distances through trilateration method. The application was carried out in the line-of-sight region.
